Case Study of Vanitas, Vol. 7, Paperback/Jun Mochizuki

"Despite the reveal of the Beast of Gaevaudan's true identity, disaster still looms, threatening not only those involved but the townspeople below. With his book missing in action, Vanitas has only vain attempts at stopping the destruction--until an unexpected ally joins the fray. Even so, he has little hope of interfering in Chloae d'Apchier's catastrophic revenge"--Back cover.
